VBNTILA'IING DEVICE ron RAILROADLCARS.

TO ALLWHOM IT MAY CON CERN:

Beit known that I, WILLIAM G. CREAMER, of the city of Brooklyn, county of Kings, State of New York, have Ainvented a. new and improved' Mode of Ventilating Railroad Cars; and I do hereby declare that the fo1- lowing is a. full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. l

The nature of my invention consists -in making openings in the sides of railroad cars for the admission of air, and inserting in the same ventilator-plates constructed to admit the air and exclude the cinders and rain, and `thus insuring a full'supply of pure air at all times. A i

To enable others skilled in the arts to make and use my invention, I will proceed to describeits construction and operation. I I I I construct my railroad car in the-ordinary way, and in the's'pace ovcr the windows I make openings through the side, of any required dimensions, (usually about eight inc hes square,) and in the openings, and flush with the outside of the car, I put my ventilators, constructed as'follows: I take sheets of tin plate and perforate them with openings, as vshown by letters A B C D, on plate 1. On the back of the sheets Isolder half-round pieces of tin, of tunnel shape, shown at A B C D, plate 2. These plates are secured on the side of the car over the openings, with the smooth side e e, plate 2, outward.

The advantages of this arrangement are that the side of' the car presents a smooth, flush surface, over which the painting and lettering can be arranged without reg-ard to the openings, and at the same time air is freely admitted, and the entrance of rain and cinders eli`ectually excluded. Ventilation is always required in a crowded railroad car, even while itis raining; and where plain openings are used it is necessary to close them in rainy weather. The plain openings are also unsightly vin appearance, (especially onl railroad cars,) causingA breaks or stops in the painting andl lettering. The plan I have described obviutes this, making a surface very nearly smooth and Eflush, over which the painting and lettering can be as neatly done as if it were a plain surface. These ventilator-plates may also be made of cast iron or other materials. They are also applicable to the ventilation of carriages, omnibuses, cabins of steam and sailing-ships, Zito.

It is easy to see that the plan I have described may be greatly modified within the range of my invention, I do not, therefore, limit myself to the precisev form of openings and construction described, but

. What I claim as my invention, 'and desire to secure by LettersPatent, is- The construction .and attachment of Ventilating-plates to the sides of railroad cars, to admit air and exclude rain and cinders, and present a flush surface, substantially as specified.
